Could Bees Take Over From Sniffer Dogs?

Humans have used dogs' excellent sniffing talents ever since our ancestors figured out that canine companions could help them track down their next meal.

But what about other animals? Can they take us beyond the limits of our own senses? That's what CrowdScience listener Beth wants to know, so we obligingly try to sniff out some answers.

After immersing ourselves in the world of insect senses at our local zoo, we visit an insect lab in Germany to find out whether sniffer bees could take over from sniffer dogs. And could ants help us fly the drones of the future? We meet the scientists trying to turn ant vision into computer code, to send robots into places GPS can't reach.
